STOVE OR RANGE.

SPECIFICATION forming part of Letters Patent No. 791,400, dated May 30, 1905.

' Application iilcdrJuly 25, 1904. Serial No. 217,919-

To a/ZZ whom it may concern:

Be it known that I, DANIEL D. BERRY, a citizen of the United States, and a resident of Springfield, Missouri, have invented certain new and useful` Improvements in Stoves or Ranges, of which the following is a specifica tion containing a full, clear, and exact dc-v 'scription, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in cook-stoves, ranges, and the like; and it consists of the novel features herein shown, described, and claimed. f

My present invention is an improvement upon my former invention shown in the patent granted to me July 7, 1903, No. 733,129. One of the principal features of my former invention consisted in placing the Ere-box directly under one end of the oven, and I have found by experience -that the corner of the oven directly over theire-box will become very hot in comparison with the remainder of the oven, and it is the object of my'present invention to improve the stove in this respect.

In the drawings, Figure 1 is a perspective detail illustrating a stove embodying the principles of my invention. Fig. 2 is a vertical central section. Fig. 3 is a vertical cross-section through the oven and looking forwardly.

Referring to the drawings in detail, the lire-box 5 is located directly below one end of the oven 6, so that the products of 'combustion may pass upwardly in front of the oven through the passage 7 and backwardly under the oven through the passage 8, upwardly back of the oven through thekpassage 9, and over the top of the oven through the passage 10 and out through the flue-opening 11. There is a tendency to overheat the lower corner of the oven which is immediately above the fireboX, and it is my object to protect this corner of the oven.

A bridge-wall 12 projects downwardly and forwardly from thev corner of the oven and extends from one side of the stove to thel other, there being a central air-passage 13 in sald brldge-Wall. A casing 14 extends from near the rear lower corner of the oven forwardly around the outer edge of the bridgewall and upwardly to a point near the upper front corner of the oven, there being inlet air-passages 15 leading from the outer air through both walls ofthe stove into the chamber 16 between the bottom of the oven and the casing 14 v'and there being outlet-passages 17 leading outwardly from the chamber 18 between the frontof the oven and the casing 14 through both sides of the stove to the outer air, so that when the air in the chamber 18 becomes rarefied by heat' it will pass outwardly through the opening 17 and cold air will pass inwardly through the openings 15 to the chamber 16 and through the air-passage 13 to the chamber 18, thus making acirculation of fresh air around the lower front corner of the oven, thereby protecting this part of the oven from overheating. A second casing 19e`Xtends from the lower end of the rear -wall of the oven down and forwardly under the oven and upwardly to the upper end of the lfront wall of the oven, thus forming an air-chamber 20. Screened openings 21 are formed through the sides of the stoveinto the oven near the upper front corners, air-passages 22 areformed through the lower ends of the rear wallrof the oven into the air-chamber20,V and air-passages 23 are formed through the casing 19 in front of the oven, so that when the'air in the front part of the chamber 2O loecomes heated and rareiied it will pass outwardly through the openings 23 and upwardly to the chimney and fresh air will be drawn into the oven through the openings 21 and pass from the oven through the openings 22 to the chamber 20. The chambers 16 and 18 take air in from the room and discharge it into the room without passing it through the oven, and the chamber 2O takes air from the room through the oven and discharges it into the chimney, thereby disposing yof any smell that might come from the oven. The chamber 2O forms a hot-blast draft to furnish hot oxygen to be united with the imperfect products of combustion above the lire-box 5, thereby consuming the smoke and gases, improving the combustion, effecting a saving in fuel, &c. The casing 19 andthe air-chamber 20 form a protection for the oven and for the IOO plate 14, thereby preventing burning out the oven and burning out the plate 14.

I claim-u 1. In a stove or range: an oven having inlet-openings 21 and outlet-openings 22; the bridge-wall12 projecting downwardly and forwardly from the front corner of the oven;

there being a passage through the bridgewall; the easing 14 extending from the rear lower eorner of the oven forwardly around the outer edge of the bridge-wall and upwardly to a point near the upper front eorner of the oven; there being inlet-passages 15 leading from the outer air through the walls of the stove to the reharnber within the casing below the bridge-wall; there being outlet-passages leading through the wall of the stove from the chamber within the easing above the bridgewall; the second easing 19 extending from the lower end of the rear wall of the oven above the discharge-openings 22 under the oven and upwardly to the upper end of the front wall of the oven; there being outlet-openings from the chamber within the second casing; substantially as specified.

2. In astove or range: the oven 6 having the inlet-openings 21 and the outlet-openings 22; the bridge-wall 12 projecting downwardly and forwardly from the oven and having a central air-passage; the easing 14 extending from nea r the rear lower corner of the oven forwardly around the outer edgeof the bridge-wall and u pwardly to a point near the upper front corner of the oven; there beinginlet-passages 15 through the walls of the stove below the bridge-wall; and there being outlet-passages 17 through the walls of the stove above the bridge-wall; and the second easing 19 extending from the lower end ofthe rear wall of the oven above the outletopenings 22 downwardly and forwardly and upwardly to the upper end of the front wall of the oven; there being outlet-passages 23 through said see-ond easing in front of the oven; substantially as specified.

In testimony whereof I have signed my name to this speeilioation in presence of two subscribing witnesses.

DANIEL D. BERRY.
